“…The proper adjustment of the Mn content in Al-Mn solid solution should boost the electrical conductivity of Al-Mn alloy to meet the industrial specification. The similar phenomena taking place in the cast Al-Fe alloys [17,18] and Mn-containing wrought Al alloys [19] were observed previously.…”

“…Hence, the PSMC Al-0.3Mn alloy capable of absorbing the energy during deformation was as tough as the PSMC HP Al (99.9%). where σt is the true stress, εt is the true strain, K is the strength coefficient, and n is the strain-hardening exponent [17,18]. The regression analysis indicated that the power expression agreed well with the tensile data.…”

An Al alloy containing 0.3 wt% Mn (Al-0.3Mn) for potential applications in electric vehicles (EV) was prepared by permanent steel mold casting (PSMC) along with high purity (HP) Al (99.9%). The microstructure of the as-cast Al-0.3Mn alloy was analyzed by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The microstructure analyses revealed that the Al-0.3Mn alloy consisted of primary Al phase, micron-sized Al-Fe-Mn intermetallic phase, and nano-sized Al-Mn intermetallic phase. The tensile properties including ultimate tensile strength (UTS), yield strength (YS) and elongation (ef) were evaluated by tensile testing. The phase sensitive eddy current method was employed to measure the electrical conductivity. The addition of 0.3 wt% Mn increased both the UTS and YS of the cast HP Al significantly to 72.3 and 20.4 MPa from 59.2 and 14.0 MPa. The evaluation of tensile behaviors indicated that the Mn addition significantly improved the resilience and strain hardening rate of the PSMC HP Al, although the toughness of the PSMC Al-0.3Mn was comparable to that of PSMC HP Al. However, the ef and electrical conductivity of the cast alloy decreased to 28.9% and 45.6 %IACS from 37.1% and 61.1 %IACS. The difference in tensile behaviors and electrical conductivities between the PSMC Al-0.3Mn alloy and the PSMC HP Al should be attribute to the emergence of a large amount (2.

“…Vehicles are also becoming larger and heavier (e.g., [67]). Estimates assumed that this resulted in the additional consumption of up to 9.2 million tons of steel in 2022 [68]. With the mass market transition to electric vehicles and the accompanying lighter-weight construction, the average aluminum content per car manufactured in Europe is expected to increase from today's 205 kg to 256 kg by 2030 [47].…”

Greenhouse gas (GHG) emissions from human activities have climbed significantly above pre-pandemic levels and have reached record highs that unequivocally accelerate global warming. Industry has a significant impact on climate change, emitting at least 21% of global GHGs and making little overall progress toward its reduction until now. Reducing industry’s emissions requires coordinated action along the value chains in order to promote mitigation options, such as energy and material efficiency, circular material flows, and transformative changes within production processes. This article is the first evaluation of GHG emissions generated during the manufacturing of vehicle components by Austrian companies. For this, the authors analyzed three different products of automotive suppliers according to the methodology of ISO 14067. Despite previous efforts toward an environmentally compatible fabrication, additional and significant reduction potentials were identified. These measures for product carbon footprint (PCF) reduction included the sourcing of low-carbon materials (which are already available on the market), more extensive use of renewable energy, and changes towards more resource efficient manufacturing processes and machinery. Depending on the materials used, the PCF can be reduced by up to 80%. The findings serve to prepare for future PCF reporting regulations and illustrate reduction potentials to achieve future market advantages, especially when PCFs become an awarding criterion.

Reducing industry’s emissions requires coordinated action along the value chains in order to promote mitigation options, such as energy and material efficiency, circular material flows, and transformative changes within production processes. The authors analyzed the GHG emissions generated during the manufacturing of three different products of automotive suppliers located in Austria. Despite previous efforts toward an environmentally compatible fabrication, additional and significant reduction potentials were identified. These measures for product carbon footprint (PCF) reduction included the sourcing of low-carbon materials (which are already available on the market), more extensive use of renewable energy, and changes towards more resource efficient manufacturing processes and machinery.
